Rocker Arm and Shaft Assembly Ford 352-428 FE

The Rocker Arm and Shaft Assembly Ford 352-428 FE by EngineQuest is a precision-engineered valve train component designed for serious FE-block builds and restorations. This assembly serves as the critical link between your camshaft and intake/exhaust valves, directly controlling valve lift and duration—two of the most important factors in engine breathing and performance.

EngineQuest manufactures this assembly to exacting tolerances, matching the specifications required across Ford's 352, 390, 406, 427, and 428 FE engines. The rocker arms are designed to handle high lift profiles while the shaft is engineered to minimize deflection under load, preventing binding and ensuring predictable valve timing across the entire RPM range. This level of manufacturing precision eliminates guesswork during engine assembly and delivers the reliability that separates quality rebuilds from budget alternatives.

This rocker arm and shaft assembly is essential for anyone restoring or building a FE-block engine, from street cruisers to competition applications. It is optimized to work seamlessly with OEM and performance camshaft profiles, maintaining proper rocker ratio and valve overlap characteristics. Installation requires careful attention to detail to ensure optimal performance and longevity.
